Brake Disc help info

[Gogo]

Hi. I wanted some help with my decision about brake disc and pads. I have Audi A6 2010 2.7 140Kw. My rear brake pads are finished and wanted to put new one. Now when i inspected the disc i saw that the thickness is 20mm. According to the manual 20mm is the minimum thickness. My question is, because i need new pads and the disc is already at its minimum thickness, should i buy new discs or is it safe to resurface these?

Hello Gorman, 

New discs will be required. 
Kind regards,

Gareth.

Ok, thank You. I ordered new pads and discs today.
